2
What is competitiveness? Countries and firms Growth and trade – the external constraint Explaining competitiveness; cost competitiveness versus ”non-price factors” – the ”Kaldor paradox” ”non-price factors” cannot be taken for granted, but needs to be explained Innovation and competitiveness?

3
A simple Schumpeterian growth model (1) Assume that the GDP of a country (Y) is a function of its technological knowledge (Q), its capacity for exploiting the benefits of knowledge (C), and a constant (A 1 ): (2) Its technological knowledge is a function of knowledge diffused to the region from outside (D) and knowledge (or innovation) created in the country (N) and, again, a constant (A 2 ): (3) The diffusion of external knowledge follows a logistic curve, where T * and T, represent the frontier country and the country under consideration

4
Why do growth rates differ? (4) By differentiating (2) and substituting (3) into it we obtain the growth of a country’s technological knowledge: By differentiating (1) and substituting (4) into it we get the country’s rate of growth: Which can be expressed in relative terms to show why growth rates differ:

5
Hence, the rate of growth may be seen as the outcome of three sets of factors: The potential for exploiting knowledge developed elsewhere. Creation of new knowledge in the country (innovation). Growth in the capacity to exploit the potential entailed by knowledge (independently of where it is created). Model applied to cross country samples by Fagerberg (1987) and Fagerberg and Verspagen (2002), both in Research Policy: All three factors matter, but imitation becomes harder through time, and importance of innovation increases

6
Including international trade... Assume a country’s market share for exports depends on three factors: its technological competitiveness, its capacity to exploit technology commercially, and its price (P) competitiveness: ExportsImports Differentiating these equations and substituting (4) into them, we arrive at the dynamic expressions for the growth in market shares:

7
The growth of market share depends on four factors: The potential for exploiting knowledge developed elsewhere, which depends on the country’s level of technological development relative to the world average. Creation of new knowledge (technology) in the country (innovation) relative to that of competitors. Growth in the capacity exploit knowledge, independently of where it is created, relative to that of competitors. Change in relative prices in common currency And specialization and demand? (Thirlwall – Kaldor)

8
The external constraint If we assume that trade is in balance, we get: Substituting the dynamic market share equations into this equation and rearranging gives us the reduced form of the model: And by including demand into the market share equations we arrive at: Which captures the 4 aspects of competitiveness:

What explains the change in technology and capacity competitiveness?

21
Convergence or divergence in the global economy? Forging ahead (technology): Asian tigers Catching up, for different reasons, EU- acceding and Asian Developing EU, ”Middle of the road”, with small EU countries doing better than large ones Falling behind, along all dimensions, former CIS/South-East Europe
